Alternator rebuild kit??
I have the car in sig with a 105 amp alternator. My stereo kills them. So far, the 105 has been ok, but I think the alternator is dieing. I put in a capacitor and cant really get it to charge up. (A .5 farad cap, its tiny.) I have a machine at my shop that tells me how much power its putting out, it reads 13.7V and 8amps. Barely charging. (Gonna REALLY check it tommorow.)
In summit, they have a part I have been kinda eyeing recently.

Anyone use this? Is it very hard to do? I am a professional mechanic, but I have never done a alternator rebuild before.

I have rebuilt many over the years, mostly Delco units. The kit you refer to is also marketed directly at www.alternatorparts.com. It is a pretty simple process, the only tricky part is unsoldering the rectifier pack before the case gets separated. Bearings are basically what you are familiar with being a mechanic. The 140 upgrade will improve the output, but not as much as you might think. GM only rates thier CS-144 unit at 124 amps under normal operating conditions, a CS-130 105 averages about 75-85 amps in the vehicle. Expect about 100-115 amps from the kit at full output. Heat dissapation has always been a problem with the CS-130, that's why they went to the "D" version. If I were you I would look around at a boneyard for a real CS-144 and even if it needs a reman just send it out or fix it yourself. It is a beefier unit with improved cooling. If you opt to do the kit one thing to keep in mind. When you reassemble it and you will know what I mean when you do it make sure you crimp tightly the stator leads before soldering. One of the local kids did one and he failed to do a good crimp and the connection go so hot the solder melted opening one phase of the stator.

Yeah, it does have a finned heatsink for the rectifier, but not as much of one do do really a whole lot of good. They still run hot as hell. The kit does give a decent bang for the buck, but the improved cooling of the CS-144 does make a difference.

My supplyier cant get a CS-144, he needs to know what kinda car it came off of. Chances are, it'll be $150-$200 anyway, I would probably just get a Iceburg kit from that link, or the nasty dual rectifiy'er version.
